Joining a new codebase is hard. Your first few weeks set the tone. A system helps you work faster.

• Start with the big picture. Learn what the app does. Who uses it? How does it make money? Read the README and design docs. Draw a diagram. This shows you your knowledge gaps.

• Run the app locally on day one. Follow the setup steps. Update the steps if they fail. This helps you and the next engineer.

• Read code in a structure. Start at the entry point. Follow the request flow. Study the data model and tests. This creates a mental map.

• Ship a small change. Fix a typo. Add a test. Improve a doc. This builds confidence. It proves your environment works.

• Pair with senior engineers. Watch how they debug. Learn how they deploy. This knowledge is often undocumented.

• Note everything. Write down team rules and design choices. Share these notes. Your fresh eyes find mistakes experts miss.

• Ask questions. No question is stupid in the first 90 days. It speeds up your growth.
